Your blog is perhaps one of the best pieces of science writings I have recently come across! Brilliant work ! I have been meaning to start something similar..now am inspired :)
By the way- . . .Read More

I'm starting as the Associate Director of the Genomic Analysis Facility at Duke University in two weeks! Hopefully once things settle down I'll actually be able to write again and start recruitin. . .Read More

The weekend before Christmas, I was sucked into a giant, enticing vortex of craving and desire, stuck for hours with the inability to leave—my only limitation being my wallet.

In other words, I went to Target.

And—again, in other words—I was like a bull in a China shop.

Back in 2009, Target introduced new gigantic, plastic, Playskool-esque shopping carts. Maneuvering the aisles is like passing a car on a one-lane country road in a Hummer.

Of course they're ridiculously cumbersome, but it's all a trick on the Target executives' part—the bigger your cart, the more you can fit in there. You'll look silly hauling around a couple packages of pens and a box of tissues to the checkout counter, after all. Better head to the appliance section and fill it with a microwave or plasma TV.

In this second installment, we'll explore how stores betray our sense of sight, tricking us to buy stuff we really don't want or need.

Retailers have—quite creepily, actually—studied our every move. In fact, they've found that we like to shop counter-clockwise, and stores with their main entrance to the right side sell more than their counterparts with doors on the left.

It's rife with redundant phrases, confusing methodologies, and tiny graphs. Reading page after page of long words in small font is better than any over-the-counter sleep aid out there for getting the job done.

Occasionally, the rare gem will come along just when you least expect it, providing a readable (dare I say—enjoyable) account of the latest research.

Dr. Perry Kendall asserted yesterday that the health risks of 3,4-methylenedioxymethamphetamine—or MDMA, the active ingredient in the drug ecstasy—are exaggerated, and that pure ecstasy is not dangerous when consumed responsibly by adults.

Its lethal dangers arise, he says, when gangs pollute the drug with other chemicals.

I'm not sure when the notion came into play that anything which doesn't kill you automatically means its "safe," but I would like to respectfully debunk Dr. Kendall's remarks with a very powerful and striking study published 13 years ago.

Specifically, MDMA induces release of the neurotransmitter serotonin by causing serotonin-containing vesicles to dock and enter the synapse. Higher-than-normal serotonin levels can result in neurotoxicity in the brain.

What, exactly, causes the euphoria from MDMA is not entirely clear; other drugs that release serotonin, such as fenfluramine, do not have this effect.

Remember those old "Just Say No" PSAs from the late '80s championed by First Lady Nancy Reagan? "This is drugs." An egg cracks into a sizzling skillet. "This is your brain on dr . . . More

Today I participated in a brain imaging study! I laid in an MRI machine for 45 minutes and looked at pictures of chocolate while smelling chocolate odors. Tough life, right? (Hershey really is the sweetest place on Earth...even in the labs!)

The MRI machine is rather big, rather loud (I wore headphones), and...rather claustrophobic—but it operates on a rather GENIUS principle! My brain was imaged every two seconds; eventually, the images will be overlaid to create a complete picture of my brain, so it was important that I remain very still.

Some of you may have undergone an MRI so a doctor could examine a particular body part due to injury or to diagnose a problem. The MRI machine works on the principle of magnetism; essentially, the images you're seeing are comprised of the nuclei of the atoms in your body.

But that can't be the case. Close your left eye. You can still see much of your left visual field, and you'd certainly smell any food placed under your nose. And what dog is one to walk away without finishing their food?

In fact, Barley is displaying signs of hemispatial neglect, a strange condition in which brain damage, despite normal vision, results in complete neglect of the left side of one's world. Barley had, in fact, suffered a stroke.

Hemispatial neglect most commonly occurs after injury to the right parietal lobe like, in Barley's case, stroke.

It is not as common with left parietal lobe damage—it is thought that the right hemisphere of the brain is generally more specialized for spatial memory, while the left side is better tuned for language.

The left side of a person's world is ignored, then—damage to the right side of the brain reduces the amount of neural activity that crosses over the left via the large fiber tract connecting the two halves, called the corpus collosum (right).

A number of strange symptoms can arise in a person suffering from hemispatia . . . More

Welcome to my new blog, neuroBLOGical! My name is Jordan, and I'm a 22-year old graduate student in the Neuroscience program at Penn State Hershey. I'm a native of the Baltimore area, and graduated from the beautiful St. Mary's College of Maryland in May with my Bachelor's in Biology and Neuroscience.

I have had an interest in neuroscience since 8th grade—that's possibly before I even knew what "neuroscience" meant. The brain fascinated me, and I wanted to learn everything that I could about the mysterious 3-lb. organ that simultaneously controlled my thoughts, speech, and movement.

I've worked in a number of labs, from cellular (a model of Huntington's disease) to organismal (salamander limb regeneration), from chemical (measuring vitamin D levels) to behavioral (RATS!). Conducting scientific research is fascinating, but can also be extraordinarily tedious. I can't tell you how many times I used to nod off in the dark microscopy room after being awake since 5 AM for my college rowing practices.

To protect myself from the occasional disappointment that sometimes accompanies failed experiments, I've always enjoyed reading about a wide variety of scientific topics, usually in popular science magaz . . . More
